The black SE730 Protective Equipment Case with empty interior and metal keyed locks from Seahorse is watertight, airtight, and crush resistant. This case has an automatic pressure purge system with an O-Ring to ensure a tight seal. This valve automatically activates upon closing the case and the pressure is released when you open the latches. This case has molded-in padlock holes that can accept TSA standard padlocks. There are four internal mounting bosses in the bottom of the case which use 1/4" self tapping screws.
The metal keyed locks are made of chromed steel.
